Their story is similar to that of George and Lennie from John Steinbeck's novella Of Mice and Men. Runt and Lennie share their lack of intelligence, while Rita resembles George's shrewd personality, as well as his responsibility to care for his mentally challenged friend. In both stories the characters travel from place to place, searching for a better life. In George and Lennie's case it's a farm of their own, while Rita and Runt are looking for a home, usually somewhere in California. The episode Of Nice and Men is a direct parody of the novella, indicating some level of resemblance was intentional.
